such a wonderful question, if you are smart the best way is to not get caught and have it appear as natural causes hence no having to dispose of body. However if disposing body becomes required, you can dislove it in chemical bath, chop up body parts, if confident about not getting caught and right connections assuming body organs are in good shape can donate them to help those needing transplants. Another example is Megan is missing if you can get the body to fit into cylinder container bury the body apparopriately in soil in some obsurce remote forest area. There is also water but more often that not those bodies are eventually discovered unless you make cut on body get blood to flow and dump in ocean where sharks are known to be. Lastly if you are friends with funeral home and can use incerator then you are left with ashes which can easily be disposed of.
